[RFC PATCH 0/6] mm/damon: misc cleanup/improvements for core, vaddr, sysfs and tests

[SJ Park <sj@kernel.org>]

Refactor code, optimize code speed, and add a missing feature support on
various areas of DAMON.

Consolidate invalid DAMOS quota charge pointers fixes into single place
in core with patch 1.  Optimize the efficiency of vaddr damos_migrate
action under filter failures with patch 2.  Implement sz_filter_passed
feature for damos_migrate action in vaddr, with patch 3.  Drop a
redundant and racy quota goal target value validation in sysfs, in favor
of that in the core layer, with patch 4.  Drop unused variables and
imports from selftests with patch 5 and 6.

SJ Park (6):
  mm/damon/core: handle invalid target in
    damos_fix_stale_charge_pointers()
  mm/damon/vaddr: advance migration attempt in folio level for filter
    out
  mm/damon/vaddr: implement sz_filter_passed for migrate_{hot,cold}
    action
  mm/damon/sysfs-schemes: drop redundant and racy zero target_value
    check
  selftests/damon/damos_apply_interval: remove unused variables
  selftests/damon: remove unused imports of os and sys modules
